WhatsApp Click to Chat Feature Have Exposed Phone Numbers of Users

Jayaram reported that Click to Chat feature of WhatsApp exposed the phone number of users on Google search. The specific feature of the Facebook-owned app allows users to generate links and share it with anyone. However, these links do not encrypt the phone number of users, and the phone numbers of users are visible on the plaintext. Also, once the link has been shared with anyone, it cannot be revoked by the user. Jayaram also explained the entire case with an example and stated that the link which WhatsApp creates does not have robots.txt file in the server root. As a result, search engines like Google and others can crawl up and index the links which will stay on the web. Due to the glitch, several cybercriminal and attackers could target the users whose personal phone numbers have been listed on Google search. Jayaram also reached out to WhatsApp and Facebook with his report.
